The planing machine feeders are built with electric drives. Feed speeds range from 20-300 m/min and mechanisms with feeds to a max. of 500 m/min have been realized.

Possible timber lengths are approximately 600 - 16,000 mm. There are virtually no limits to the possibilities of the mechanization. Usually the closely-formed packets are supplied to the planing machine feeder via tilting destackers and transverse chain conveyors. Planing machines can also be fed via vacuum technology or push-off technology. Also use of various scanner systems, for measuring moisture, cupping, quality, and for testing strength, as well as for attaching barcodes, is possible.

Kallfass also offers the possibility of bringing strips and boards to the desired length before or after planing, with the aid of the multiple crosscut saw. The strip bundling system developed by Kallfass (patented) can be placed downstream from a planing machine and thus enables clean bundling and subsequent stacking of split boards and strips.
